Abstract: A system and method for measuring an inside diameter of a pipe to determine if it exceeds a predetermined value using a plurality of fingers operatively connected to a spring. When in a fully extended position, the distance between opposite fingers is the predetermined value. The fingers are pivotable between a starting position, through the fully extended position, and to a failing position. In the starting position, an outer end of each finger engages an inside surface of the pipe to compress the spring. If the diameter exceeds the predetermined value as the system moves through the pipe, the pipe inside surface will no longer engage the fingers, which releases the spring causing the fingers to pivot to the failing position, where they remain until the system is removed from the pipe and manually reset.

Abstract: Disclosed is a workpiece diameter measurement method including the steps of: measuring coordinates of a point P that is on an outer circumferential surface of a cylindrical workpiece that is supported such that a rotary axis of a main spindle of a machine tool and a central axis of the cylindrical workpiece coincide with each other, the coordinates having a maximum or minimum coordinate in a first direction that is orthogonal to the rotary axis; calculating a distance D2 in the first direction between the point P and a reference point Q that is a point at which a distance D1 in the first direction from the rotary axis is known; and calculating a workpiece diameter of the cylindrical workpiece based on the distance D1 and the distance D2.

Abstract: Generally, a device to measure the circumference of circular objects. Specifically, a device including a pair of slidingly engaged members disposed between a pair of arms configured to be engaged with tread on a tire at about the midline of a wheel, an electrical circuit which varies in output voltage based on the distance between the pair of arms, and a processor communicatively coupled to a non-transitory computer readable medium containing a program which correlates the output voltage of the electrical circuit to a unit measure of distance between the pair of arms and calculates tire circumference.

Abstract: A weaving installation includes a loom that receives a series of strands, and at least one device for measuring the diameter of a strand having a defined number of filaments. The device includes a diaphragm having an external ring forming a support on which a series of strips forming an iris are fixed. The strips are movable and allow a substantially circular space with variable dimensions to be defined at the center of the iris. The diaphragm is configured to adjust the dimensions of the space so as to allow a strand of the loom to pass through it, and to encircle the profile of the strand so as to allow the number of filaments in the strand to be determined.

Abstract: An inspection and measurement device includes a body defining a first planar face within a first bounded area, a first reference feature disposed on the first planar face within the first bounded area and corresponding with a first measurable parameter, and at least a second reference feature disposed on the first planar face within the first bounded area and corresponding with a second measurable parameter. The first and second reference features are positioned within the first bounded area for placement adjacent an element bearing the respective one of the first and second measurable parameters. The first and second reference features overlap within the first bounded area in at least one direction.

Abstract: A cable measuring tool includes a first end portion and a second end portion. The first end portion includes a first rounded edge and a cutaway. The cutaway is configured to fit at least a half of a cable having a maximum diameter. The first rounded edge has a radius greater than the maximum diameter of the cable. The second end portion is opposite from the first end portion. The second end portion includes a second edge. The first rounded edge of the first end portion and the second edge of the second end portion define a length of the cable measuring tool.

Abstract: The invention provides a solution according to which the diameters of a large plurality of cylindrical measuring pins (1A-1E) can be measured fast and accurately, while using an affordable, non-complex and universally applicable measuring apparatus. In concise summary, the key features of the invention are formed by using a two-dimensional tracing apparatus (10) having a simultaneous holding structure (12) for simultaneously holding the measuring pins in fixed positions relative to the apparatus frame (11), while the measuring pins are alongside one another with their central axes parallel to one another, and by performing first and second joint tracing operations by tracing against and along diametrically opposite first and second parts of first and second circular sections of the cylindrical outer surfaces of the measuring pins, to thereby determine measured values of the diameters.

Abstract: A device used in a spindle or fixture to measure tool sizes. The device has two cylindrical shapes that have precision machined surfaces. The device's face has a precise size which is the same nominal size as that of a material removing tool. The device's shaft allows for concentric and precision fastening of the device to a spindle or a fixture. The nose of the device is located on the end of the larger of the two cylindrical shapes which is visible exposed when mounted and used. The end of the device is at the end of the smaller of the two cylindrical shapes which is hidden after mounting. The device allows more accurate programming of machine tools thus providing higher quality results on machined work pieces and reducing machining cycles.
